Shall we work less, that grace may abound?

The evangelical doctrine of salvation by faith alone gives rise to a cynical attitude towards those who do charity.

It makes adherents of the doctrine feel that charity workers are doing it just to earn a place in heaven, no mayer how sincere and altruistic they are.

Is this just a minor misinterpretation of a sound doctrine, or is it a sign that the doctrine itself is fundamentally flawed?
